Observed for the first time in the world, how the planet is born.

We announced today that it has observed for the first time in the world, how the planets made ​​of rock, such as Graduate University for Advanced Studies research team, like the Earth and Mars will gather dust around the star is born. That results which help you unravel the mystery of the birth of the planets in the solar system.
Use (Hawaii, USA) Subaru Telescope, the team observed the "J1604" star of Scorpio are about 470 light-years away from Earth.
Where taken with an infrared camera how the dust turns into a disk around the star, we analyzed the image, we will gather to take shape dust, such as "arms" have been attracted by the gravity of a planet being born I caught a look. Of how the planet can go with several hundred times the mass of the Earth.
The observed star was born just about 3.7 million years ago. Mass has been analyzed for the same extent as the sun, "and may lead to the elucidation of the mechanism by which the planets of the solar system was born" (astronomy) is assistant professor of the university Mayama. Progress in observation technology is made to surprise while now. By all means, please find a clue to elucidate the mechanism of the birth of the solar system.


総合研究大学院大学などの研究チームが、恒星の周囲のちりが集まって地球や火星のように岩石でできた惑星が生まれる様子を、世界で初めて観測したと発表した。太陽系の惑星誕生の謎を解明する手がかりになる成果という。
　チームは、すばる望遠鏡（米ハワイ島）を使い、地球から約４７０光年離れているさそり座の恒星「Ｊ１６０４」を観測した。
　恒星の周りをちりが円盤状に回る様子を赤外線カメラで撮影し、画像を解析したところ、誕生しつつある惑星の重力でちりが引き寄せられて「腕」のような形になって集まっていく様子をとらえた。地球の数百倍の質量を持つ惑星ができていく様子という。
　観測した恒星は約３７０万年前に誕生したばかり。質量は太陽と同じ程度のため、同大の真山助教（天文学）は「太陽系の惑星が誕生したメカニズムの解明につながる可能性がある」と分析している。観測技術の進歩には今更ながらビックリさせられますね。ぜひ、太陽系誕生のメカニズムを解明する糸口を見出してください。
